Friedensreich Regentag Dunkelbunt Hundertwasser[a],
which was the full name he chose from himself, was an Austrian architect and painter. The three buildings in
Vienna that he designed stand out: The Spittelau Incineration plant, the Vienna House of Art (Kunst Haus Wien),
and the low-income housing block that bears his name: The Hundertwasser House.

Next to the house (across the Kegelgasse) is "Hundertwasser Village", which is
a bit of a tourist trap, I suspect, but which is also a very small mall
designed in the Hundertwasser-style. It has a small gallery of prints (mostly
Gustav Klimt and Hundertwasser).
